Pomham Rocks Light was built in 1871 to aid shipping in the busy port of Providence. Although the original light has been replaced by a steel tower, the caretaker of the island lives in the keeper's dwelling, now owned by Mobil Oil Company.

Conanicut Island Light, on the northern tip of the island, is not
only deactivated, but at first glance, it no longer looks like a
lighthouse. It is now a private dwelling, however, the railing from
the former lantern room is still visible on the roof of the tower.
